Three new species of Poltys spiders collected from Hainan Island, China, are described under the names: Poltys ellipticus sp. nov., P. hainanensis sp. nov. and P. pygmaeus sp. nov.
Three newly recorded species of the genus Pardosa from China are described: P. bukukun Logunov & Marusik, 1994, P. graminea Tanaka, 1985 and P. lugubris (Walckenaer, 1802)
Myrmarachne borneensis G. Peckham & E. Peckham, 1907 and M. shelfordii G. Peckham & E. Peckham, 1907 are redescribed here based on type specimens. The lectotype of M. shelfordii is designated.
The paper presents descriptions of three new opilionid species: Egaenus turkmenicus sp.n. ( ?? ), Phalangium kopetdaghensis sp.n. ( ?? ) and Graecophalangium karakalensis sp.n. ( ?? ) from Turkmenistan. All species are diagnosed, described, figured, and their distributions are mapped.
Distributional data for the millipedes occurring in the Ryukyu Archipelago and adjacent islets (Senkaku and Daito Groups) are summarized based on an extensive literature survey. There are at least 58 species and one subspecies of millipedes known from the Ryukyu Archipelago (50 of these are native and 8 introduced), 5 species in the Senkaku Group, and 7 species in the Daito Group. Of these, the greatest diversity of indigenous millipede species (32 species) occurs in Okinawa-jima Island. Our results contribute to the knowledge of the millipede fauna in the region beyond the limited account presented in the previous reviews. The results also suggest that large portions of the Ryukyu Archipelago have been poorly sampled, and that further collections would considerably improve the present inventory.
